US Patent 12011625 Fire extinguishing capsule

A sealable capsule configured to contain one or more fire extinguishing materials is provided. The sealable capsule can include an upper and a lower shell, an internal bladder and a mechanism for releasing the fire extinguishing materials. The upper shell can include a valve, one or more through-holes filled and sealed with a corresponding number of plugs, and one or more rods, each extending from the plug to an internal plate of the releasing mechanism. The upper shell can be configured to contain a first fire extinguishing material, and the lower shell can include a membrane configured to contain a second fire-extinguishing material. The bladder can be coupled to the internal plate and to the upper and lower shells, such that the bladder is positioned within the capsule in a first position when the capsule is prepared for use and in a second position when the capsule has been activated.
